CHICAGO, ILLINOIS, A CORPORATION or DELAWA F SELECTiNG APPARATUS aThepresent invention relates to selecting. apparatus and more particularlythe invention relates to apparatus selectively responsive to codecombinations of selecting conditions especially adapted for theoperation of printing telegraph mechanisms.

In printing telegraph apparatus of the permutation code ype, selectingmechanisms are employed th t are operated in accordance with receivedcode combinations of impulses to selectcharacters to be printed on atape or page. The energy. received over the line'available for the.control of the selecting mechanism is usually comparatively small, andit is therefore desirable to provide selecting mechanisms readilyresponsive to comparatively small currents. Also because of'the highspeed of operation demanded in modern printing telegraph oporation it isdesirable to reduce to a minimum the operations of the selector andprinting mechanisms to increase the durabilityandlife of and to reducethe wear and tear on the mechanisms as much as possible.

Accordingly one of the objects of my invention is to provide selectingapparatus in which a minimumamount of energy is required to control theselective operation signalling conditions;

A further object, of the invention is to provide novel selectingmechanisms embodying a plurality of permutation elements moved only in asingle direction to differ: ent settings for succeedingselectingcombinations.

Still further objects of my invention are such as may be. obtained byutilization-of and interposed I Application filed January 12, 1929.Serial No. 882,186.

As shown in" the drawings energy is supplied to,the mechanism by a motor(not shown) which drives shaftl; Mounted on and rotatable with shaft 1is gear 2 which meshes witheand drives gear 3. Gear 3 is supported onand drives main selector printing and drive shaft 4. Secured to gear 3by-suitable screws 5 is a typewheel 6 on the circumference of which aremounted the letters of the alphabet, numerals, and characters to beprinted as indicated at 7.

Shaft 4 is-journaledin anti-friction bearings 8 supported in printerside frame mem-- bers 9 and journalled on central section 10 thereofbetween side-framesi 9 are six selecto'r disksv 11 and a selectoroperatin disk 11 Slidably ke ed on section 10 of s aft 4 etween adjacentones of disks 11 and the disk 11 are friction drive clutch'disksi12 acoil spring 13 (Figure 3) interposed between discs 14.; and 15 reach ofthe notches 19 as shown.

pawls 21' is mounted on and rotatable with.

- As shown in Figures 4 and 7 to 13, each' selector disk has one or morestop notches 19 cut inits circumferential edge, adapted to be engaged bynoses 20 of the selector eon-' trolling pawls 21. Two pawls 21positioned diametrically opposite each other are provided for each ofthe disks 11, while one pawl is provided for the disk 11. As shown bythe arrows (Figures 7 to 13) the disks tend to rotate counter clockwisein operation but are normally held from rotation by noses 20 of the pairindividual to each disk 11 being normally engaged with one Each of the ashaft 22 individual thereto by means of set screw, 23.

As will be clear from the description thus far given the disks 11 arenormllay held from rotation by the noses 20 of pawls 21 which engagenotches 19 in these disks; As

will be described hereinafter, pawls 21 are selectively rocked in aclockwise direction in accordance with received code combinationsreleasing selected ones of the disks for rotation until the next notchin the released disk is engaged by the opposite pawl individual thereto.

Shafts 22 are rotatably journalled in suitable bearings formed in sideframes 9 and secured to the right ends thereof as viewed 7 in Figure 3are the marking control levers 25 and spacing control levers 26controlling the positions for discs 11, and the selector operatingcontrol lever 26' controlling the operating disk 11'.

Pawls 21 and arms 25,7 26 and 26' individual thereto are so arrangedthat the noses, 20 thereof ride on the periphery of disks '11 and 11'and drop into notches 19 by the action of gravity in operation of themechanism.

An operating lever 27 is provided to selectively actuate levers 25, 26and 26' in accordance with received combinations of signallingconditions as will more fully hereinafter appear. Lever 27 is slidablysupported on dowels 28 and 29 carried by plate 30 iotatably mounted onthe end .of,maindrive shaft4. Plate 30 is frihtionally driven by mainshaft 4 through friction disk 31 and clutch plate 32, splined forlongitudinal movement on the main drive shaft 4. Friction disc 31 isforced into frictional engagement with the plate 30 by means of a spiralspring 33 interposed between bearing 8 and c utch plate 32. As shown inFigure 4, in

Rotatably connected to the central portion of arm 27 is one end of alever arm 36, the opposite end of which is pivotally connected by meansof a pin 37 to the armature 38 of the line electro-magnet 39; Magnet 39inay be of any well known construction but is preferably a sensitivepolarized magnet provided with a magnetized core 41 and divided windings42. As shown, arma ture 38 extends through windings 42 and is pivotallysupported at 43 between the sectionsof winding 42 and is limited in itsmovement by the poles 44 of core 41 As the armature 38 oscillates onpivot 43 in response to energizations of windings 42 it in turnoscillates the'lever arm 36 in a longitudinal direction and lever 27 isin turn moved axially with respect to the main shaft 4. At the extremeleft position of the armature 38 the path of the arm 27 as it rotatesdoes not include control arms 25, but does include the control arms 26and 26', and when armature 38 is moved by the electromagnet to itsopposite or right hand position-in response to a marking impulse and thearm. 36 accordingly moves lever 27 to its right hand position in Figure3, the path of the rotating arm 27 includes control arms 25 and not thecontrol arms 26 and 26. Accordingly as lever 27 is rotated by shaft '4it will engage and rock the control arms 25, 26, and 26 in a mannerdepending upon the energizationof magnet 39.

' The electromagnet 39 is operated in response to received codecombinations of impulses, the magnbt being as is well known' in the art,responsive to impulses transmitted over a signalling line extending froma remote transmitting station. The shaft 4 is driven at such a speedthat the arm 27 is rotated in synchronism ,with the signalling impulseso that it is successively in operative position with a pair of arms 25and 26 associated with a disk simultaneously with the receipt of aselecting condition allotted to the particular disk controlled thereby.As the lever 27 comes into operative relation with a pair of arms 25 and26,

the character of the received impulse at that instant will determinewhether the lever 27 will be movedinto engagement and rock thecorresponding marking or spacing control arm 25 or 26. As lever 27rotates past each pair of control arms 25 and 26 individual to theselector disks either an arm 25 or an arm 26 is moved a distancesuflicient tion by the opposite pawl 21 individual thereto, then thedisk is in proper position.

for the selection and no rotation thereof will occur. It willaccordingly be seen that rotation of selector disks occurs only whennecessary to shift the position thereof for the succeeding selection,thereby reducing the disk movements tea minimum. It will therefore beclear that the selector disks have no normal position to whichthey arerestored, but are latched in their marking or spacing positions until achange is required in a succeeding selection, and that receivedselecting impulses merely function to operate the latches to release thedisks when necessary to permit movement to the position 1n accordance.with the character of the received impulse or condition: In.

this manner all of the selcctor disks are operated in accordance' withthe received .code combinations of impulses and assume a predeterminedrelative position with respect toeach other at the end of the codecombination of impulses.

The nature of these disks and the manner in which they cause theprinting of a predetermined character after they are set up 'in aredetermined alignment .will now be described. Referring to Figures 7 to13 it will be noted that the disks lleach of which, as will be clearfrom the above, having a marking andbpacing position, is provided with aseries of small holes 51 arranged differently in each disk so that foreach different combination of the disks a different set of holes 51 willbe aligned. Loosely carried ineach of these holes 51 is a ball 52"(Figures 3 and 6) of a diameter selecting conditions is preceded by astart condition which frees lever 27 from engagement with stop 35 for acomplete revolution, and is followed by a stop condition which causeslever 27 to engage stop 35 and come to rest at the end ,of eachrevolution. For any one combination of positions of the ,disksdetermined hycode combinations of selecting conditions there is only onealignment of the balls possible and this alignment will invariabl occurfor the same relative positions 0 the disks. Similarly at other relativepositions other openings and other balls will be aligned at other positions about the circumference. For each setting of the first fivedisks11 there can be 32 such alignments bypermutation.

In order to eliminate the need of the shift mechanism controlled by acode combination of signals I provide a sixth disk 11 which is operatedin response to a shift impulse. So long as characters in the same caseposition are to be printed this disk is not operated. \Vhen however, acharacter in a different case position is to be printed, the shiftcontrol disk 11 is released for rotation causing printing in theopposite case from the preceding character as will be described morefully hereinafter.

The receipt of each code combination of signalling conditions and thecorresponding alignment of the disks 11 selects the character and theselection is then transferred by the operation of disk 11' which isinvariably released by actuation of control arm 26' by engagement withlever 27 near the end of its revolution. Disk 11 has a hole 51 and ball52 for each possible alignment of the disks 11 so that when it isreleased one of the balls 52 thereby will be moved into alignment withthe aligned balls in disks 11 thereby forcing the aligned balls to theleft inv Figure 3.

Opposite each position of alignment of balls 52 there is provided asetting pin 53 slidably mounted for longitudinal movement in suitableholes formed in the left side frame 9. Each pin 53 is provided with twogrooves 54 and 55. A coil spring 56 nesting in an annular groove 56' ofside frame 9 snaps into grooves 54 or 55 and holds pins 53 in thepositions where set. After each printing operation as will more fullyhereinafter appear pins 53 are restored to their right hand position inwhich the spring 56 lies in the left hand groove of each of these pins.As illustrated when the balls opposite one of these pins are inalignment and disk 11' is operated, the aligned balls push toward theleft (Figure 3) and move a selected pin 53 opposite which they are inalignment in a longitudinal direction toward the left against the actionof the locking spring 56. The selected pin 53 is then in operatedposition to the left with its end protruding beyond the other pins andspring 56 maintains the selected pin in operative position. From theabove it will now, be clear that one ofthe setting pins 53 is selectedin accordance with thersetting of the disks 11 and shifted to operativeposition. As will now be described the setting pin 53 selected andoperated in turn determines which of a pair of characters on the type- II wheel contains the character to beKprinted, while the sixth disk 11determines which of the selected pair of characters is to be printed.

Referring to Figures 5 and 6 it will be seen that carried on the shaft 4is an arm 61 secured to and rotatable with the shaft 4. Pivotallymounted on the end of the arm 61 by means of pin 62 is a seeker member63 provided with an extension 64 and a tooth 65. The seeker member 63 isnormally urged in a clockwise direction about its pivot 62 by a spring66 secured to the end thereof and to the arm 61in any suitable manner.

Journalled on drive shaft 4 is a hub 67 of ratchet 68 provided withteeth 69 (Figs. 3, 5 and 6). Also secured to hub 67 is printing cam disk71 having cam surface 72. The printing cam-disk 71 and ratchet 68 arenormally held from turning. by jockey lever 73. Jockey lever 73 issecured to one end of shaft 74' which is suitably journalled in theframe work. A printing arm 75 is secured to and actuated by the oppositeend of shaft 74 and carries at its free end the printing roller 76around which tape 77 passes. Feed roller 79 in frictional engagementwith the tape 77 forces the tape against roller 76 and is actuated by aratchet feed' mechanism-of anywell known construction (not shown) tofeed the tape aletter space following each printing operation. Securedat one end to the base of the frame is a spring 81, the other end ofwhich is secured to the extension 82 of the crank 73 and holds the endof jockey lever 73 resiliently in engagement with cam surface 72.

The operation of the above described a A paratus will now'be given. Ashas alreac y been explained, shaft 4 is continuously driven in operationby the power supplied from the motor through motor shaft 1, and gears 2and 3. Continuously rotating with the shaft 4 is the typewheel 6carrying the type characters to be printed. In frictional drivingengagement with shaft 4 is also the normally latched member 27 whichafter being released by a start impulse is successively brought inoperative relation with either arm of the set of control arms 25 and 26individual to each of the selector disks 11. Lever 27 is brought intooperative relation with each pairof arms 25 and 26 simultaneously withthe receipt of a selecting condition by electromagnet 39 and dependingon the character of selecting condition received at the instant when thearm 27 comes into operative relation with each pair of arms theassociated selector disk is released for rotation if it is not properlypositioned for the selection. In this manner each of the disks 11 issuccessively operated in accordance with thecode combination selectingconditions received and will be positioned accordingly to align acorresponding set ofballs 52. j

As has been explained, the'fi rst five disks 11 assume a positionpermitting either a may be utilizedwith the letters and charactersarranged in aligned pairs at each angular position of the wheel and ashift mechanism controlled by the sixth disk 11 may be utilized todetermine the printing 2 the aligned balls to'its operat've position inthe path of the extension 64 o the seeker 63 as shown in Figures 5 and6. The selected pin 53 is held in set position by spring 56," and thedisks 11 and 11' may nowbe immediately reset by the succeeding codecombination while the printing of the selected character proceeds thusproviding an overlap of selecting and printing operations. Thereafterand during the succeeding revolution of lever 27,- whilethe printingonerations now to be described take place, the selector disks llvare setin accordance with a new code. v

The arm 61 with seeker 63 is continuously rotating, driven by the main'drive shaft 4 on which it is mounted. means of, the spring 66 theextension 64 of seeker 63 is held in a pathjoppo'site the setting pins53. \Vhen the seeker 63 reaches the selected pin 53 which has been movedto 1ts operated position extension 64 will engage the protruding end ofthis pin and as the arm 61 continues to rotate the extension 64 willrotate about its pivot pin 62 against the tension of spring 66 and thetooth 65 will engage one of the teeth 69 on the ratchet 68. As describedabove, the ratchet 68 and printing ratchet 71 are loosely mounted on themain shaft 4 but normally held from 'rotation by the jockey 73 whichnormally lies in one of the depressions. of cam surface 72 such as 85.When tooth 65 engages one of the teeth 69 on ratchet 68, the ratchet isrotated a distance-to move cam disk 71 a distance of one cam depression.At the I is restored under the action of spring 66 and tooth 65disengages from the tooth 69 of ratchet 68. a

As a result however of this movement of the ratchet 68 and printing camdisk 71, the jockey 73 is rocked as shown in Fig. 5 by operation of thecam disk and shaft 74 is rotated in a clockwise direction, and printingarm 75 on shaft 74 is rotated in a clockwise direction impacting tape 77momentarily against the character on'the typewheel 6 adjacent roller 76.A character is thus printed on the tape 77. Onv continued movement ofcam disk 71 completing the distance of one tooth, jockey 73 again slidesinto a depressed portion of the cam and the shaft 74 is rocked in theopposite direction by tension of the spring 81 -moving the printingroller 76 away from the typewheel.

- This movement also produces a rotation between roller 79 and printingroller 76 to move the tape a distance of one letter space for presentinga new printing surface by operation of a suitable stepping mechanism ofany well known construction (not shown). lhe cycle of operations is nowcompleted and is repeated for each character to be printed.

It will be clear to those skilled in the art that the holes 51 in whichthe balls 52 are inserted may be arranged in any desired manner in orderto provide the necessary number of selections. In. the form shown inFigure 14 one of the selector disks 11 is provided with one tooth andthirty two holes arranged on a semi-circle of the disk, the diskmovements being a half turn. The next selector disk in this form isprovided with two teeth and two groups of sixteen holes symmetricallyarranged in one quarter of a turn, the disk movement being one quarterof a turn. The third selector disk is provided with four teeth and 6four groups of 8 balls each symmetrically arranged in one eighth of-aturn with a of two balls symmetrically arranged with an esca-pement of1/32 of a turn. The sixth disk is provided with 32 teeth, one ball beingsymmetrically arranged in 32 groups with an escapement of 1/64 of aturn. The seventh disk in this form of invention is similar to the sixthdisk but controlled by only one pawl which is actuated every time thearm 27 makes a revolution.

It willalso be understood bythose skilled in the art that the alignmentof the selector disks need not necessarily function to set balls foroperating asetting pin to control a typewheel. As shown in Fig 15 thedisks may be provided with gear teeth 91 which mesh with teeth 92 onselector bars 93 of the notched type which are operated in variouscombinations in accordance with the positioning of the disks to controloperation of a printer, or other selecting mechanism, or as shown inFig. 16 each of the disks may be provided with a notch 94 in which anextension lever arm 95{ individual to each of five vanes 94 is operatedas the disk rotates to in turn set the vanes in combinations to controloperation of selective mechanisms comprising notched code barscontrolled by the vanes in mechanisms of a type well known to thoseskilled in the art.

Instead of the arrangement for rotating the selector disks shown inFigure 6, the arrangementshown in Figures 15 to 17 may be employed Inthese modifications, a setting marking pawl 95 individual to eachselector disk is adapted to be actuated by lever 27 and through lever 96pivoted at 97 actuates link 98 secured to the selector disk Mat 99 toset the disk to marking position. A resiliently supported jockey roller101 in slot 102 of each disk 11 and 11 holdsthe disk in position whereset. In response to a spacing impulsearm 103 individual to each disk andsuitably pivotally supported on the frame work is engaged by lever 27,and rocks arny104 through a suitable shaft 104. Each arm 104is forked atits end and engages a pin 105 on the disk individual thereto. As thepawl 103 is rocked, arm 104 through pin 105 rotates the disk to itsspacing position. In thismanner each disk is operated to either positionand remains set until its position is to be changed in a suc-. ceedingselection without the use of springs; These arrangements will be wellunderstood by those skilled in the art as obvious ap- 0 plications ofthe selector disks, it beingunderstood that the inventionu'esides not inthe actual type of control accomplished there by but in the manner ofsetting these disks to any one of a plurality of non-normal positions"and maintaining them set in that position.
